This is done in two locations:

1) determines if the "account" in question is to be included with auto email retrieval (if IT is turned on).

Found under Tools | Options | E-Mail Tab | Accounts button. The auto-retrieve check box. (Note: it is generally recommended that you also check auto-delete if you are auto-retrieving. There are clearly exceptions.)

NOTE: If this question has been answered, be sure and MARK the reply that is the correct answer. There are those within the community that monitor and track "unanswered" questions. By flagging it as answered, they will know your needs have been met.
